OK X3DJSAIL finally has a test harness in place.  The invocation for new ant task <junitlauncher> still fails, but direct invocation of the class works.

X3D Java Scene Access Interface Library (X3DJSAIL) provides a set of unit tests in org.web3d.x3d.tests.FieldObjectTests to check these regexes against default and alternative values.  Initial tests in place for SFBool, SFInt32, SFFloat.

Ant stylesheets/java/build.xml target in X3DJSAIL project:
	
<target name="test.junit5.directly" description="Test X3DJSAIL using JUnit5, direct invocation of code" depends="antVersionCheck">

test output:
=====================
test.junit5.directly:
FieldObjectTests start...
FieldObjectTests.fieldObjectInitializationsTest() start...
Preliminary tests...
SFBoolObjectTests...
SFInt32ObjectTests...
SFFloatObjectTests...
FieldObjectTests.fieldObjectInitializationsTest() complete
FieldObjectTests complete
=====================

Example excerpt shows how tests are typically structured.  Am striving to show support for detecting both correct and incorrect values.

     @Test
     @DisplayName("Test SFFloatObject single-field single-precision floating-point number")
     void SFFloatObjectTests()
	{
         System.out.println ("SFFloatObjectTests...");
         SFFloatObject testSFFloatObject = new SFFloatObject(); // static initializer is tested, might throw exception
         assertTrue  (testSFFloatObject.matches(),         "testSFFloatObject.matches() tests that object initialization correctly matches regex");
         assertEquals(0.0f, SFFloatObject.DEFAULT_VALUE,   "test correct default value for this field object");
         assertTrue  (SFFloatObject.matches(SFFloatObject.DEFAULT_VALUE_STRING),
                                                           "SFFloatObject.matches(SFFloatObject.DEFAULT_VALUE_STRING) tests that object initialization correctly matches regex");
         
         testSFFloatObject.setValue(1); // returns void because it matches (overrides) Java SAI specification interface
         assertEquals( 1.0f,testSFFloatObject.getValue(),  "tests that setting object value to 1 results in value of 1.0f");

         assertEquals(-1.0f,testSFFloatObject.getValue(),  "tests that setting object value to -1 results in value of -1.0f");
         
         assertTrue  (SFFloatObject.matches( "0"),      "SFFloatObject.matches( \"0\")   tests correct string value");
         assertTrue  (SFFloatObject.matches( "1"),      "SFFloatObject.matches( \"1\")   tests correct string value");
         assertTrue  (SFFloatObject.matches("-1"),      "SFFloatObject.matches(\"-1\")   tests correct string value");
         assertTrue  (SFFloatObject.matches( "0.0"),    "SFFloatObject.matches( \"0.0\") tests correct string value");
         assertTrue  (SFFloatObject.matches( "1.0"),    "SFFloatObject.matches( \"1.0\") tests correct string value");
         assertTrue  (SFFloatObject.matches("-1.0"),    "SFFloatObject.matches(\"-1.0\") tests correct string value");

         assertFalse (SFFloatObject.matches("true"),    "SFFloatObject.matches(\"true\") tests incorrect boolean string value");
         assertFalse (SFFloatObject.matches("blah"),    "SFFloatObject.matches(\"blah\") tests incorrect alphabetic string value");
         assertFalse (SFFloatObject.matches("0 1"),     "SFFloatObject.matches(\"0 1\")  tests incorrect array as string value");
         assertFalse (SFFloatObject.matches("0.0 1.0"), "SFFloatObject.matches(\"0.0 1.0\") tests incorrect array as string value");
     }

all the best, Don
